What Are Topics?

Reappt is built around a publish-subscribe data distribution model. It uses Topics as the entities that data is published to. Clients then subscribe to these topics to register interest in the data that they contain. Topics are created in Reappt by clients with the topic control role assigned to them. These are the clients which he usually at the back end of your system, that publish the data into Reappt.

Watch the short 5 minute video, which showcases everything you need to know about topics when you sign up for Reappt.
